A Cadet Becomes a Prophet?!

Fernan Fallenberg is the young heir of House Fallenberg, one of the Empire's most prestigious houses, and a top student at the Imperial Academy. However, he's infamous for something else: his obsession with money. As a ruthless money-hound, he only acknowledges those who bring him profit and views everything in the world through the lens of monetary value. People avoid him, finding his greed repulsive. But was divine punishment finally upon him? One day, out of nowhere, disaster strikes Fernan like a bolt from the blue. As his consciousness begins to fade, something attempts to invade and take over his mind, but Fernan forcefully expels it instead. From that moment on, he begins to see something strange: a prophetic book that reveals the future. And not just any future, but a prophecy of the end of the world.
